Grill Box Fire Cooking System

British made charcoal grills and modular cooking frames for serious live fire cooking.

The Grill Box Fire Cooking System is a versatile charcoal grilling platform designed for both passionate home cooks and professional chefs. Built in Somerset, England, each Grill Box grill is crafted from heavy duty stainless steel and engineered for exceptional durability, performance and flexibility when cooking over charcoal or wood embers.

At the heart of the range is the Grill Box Konro Grill, a powerful stainless steel firebox that produces intense radiant heat ideal for traditional charcoal cooking. Used on its own, the Grill Box functions as a Japanese style konro or hibachi grill, perfect for skewers, seafood, vegetables and steaks cooked over glowing charcoal.

What makes the Grill Box unique is its ability to expand into a complete live fire cooking system. A range of interchangeable cooking frames and accessories allow the grill to adapt to different cooking styles, from adjustable Asado grilling to multi level Robata cooking.
Whether used in an outdoor kitchen, restaurant service or backyard setup, the Grill Box offers exceptional control and versatility for charcoal cooking.

Built in Britain for Serious Fire Cooking

Every Grill Box grill is designed and manufactured in Somerset using premium materials and precision engineering.

The grills are constructed entirely from 304 and 316 stainless steel, with material thickness ranging from 2 mm to 8 mm, creating an incredibly strong and durable cooking platform.

The Grill Box firebox is insulated with 25 mm vermiculite fire bricks, a natural material with very low thermal conductivity. This insulation helps the grill maintain stable temperatures while improving energy efficiency and protecting the steel body from extreme heat.

The vermiculite lining can withstand temperatures of up to 1000 °C, making the Grill Box perfectly suited to serious charcoal cooking.

The Grill Box Konro Grill forms the core of the Grill Box Fire Cooking System.

Used on its own it functions as a powerful konro style charcoal grill, producing intense radiant heat ideal for yakitori, skewers and high heat grilling.
